Intelligent digital display stepless speed regulation controller for feeder

Abstract

The invention discloses an intelligent digital display stepless speed regulation controller for a feeder. The intelligent digital display stepless speed regulation controller is formed by connecting a safety circuit (1), a reset switch (2), a self-locking circuit (4), a transformer (15) T1, a rectification voltage-stabilizing circuit (5), a power source indicating circuit (6), an input setting circuit (7), a relay J1 driving protective circuit (14), a relay J2 driving circuit protective circuit (9), a material fling indicating circuit (8), a relay J1, a relay J2, a speed regulation driving output circuit (10), an output protective circuit (11), an emergency switch (3), a wiring terminal (12), a driving display circuit (13) and a zero cross detection circuit (17) in an electric-loop mode. According to the intelligent digital display stepless speed regulation controller, a single chip microcomputer with an AD interface is adopted as a core control component, input setting is easy, and the intelligent digital display stepless speed regulation controller has the advantages of being good in control performance, stepless in speed regulation, synchronous in output, high in working reliability, and simple in structure, and facilitating production and adjusting.

Description

technical field [0001] The invention relates to a controller, in particular to an intelligent digital display stepless speed regulation controller of a feeding machine. Background technique [0002] With the development of mechanization in the aquaculture industry, feeding machines are widely used, and the work of feeding machines is realized by the controller. Up to now, there is no stable stepless speed regulation controller, and some only use mechanical A timer is used to control the length of the start-up time. The speed regulation adopts a rectangular wave composed of a time base block, a band switch, and a resistance-capacitance element to change the duty cycle, and drives the thyristor to change the output voltage. The stepped speed regulation. Due to the influence of the performance of electronic components, parameter accuracy, poor contact of mechanical contacts and the use environment, the failure rate of mechanical timers is extremely high, the speed regulation of...

Problems solved by technology

Due to the influence of the performance of electronic components, parameter accuracy, poor contact of mechanical contacts and the use environment, the failure rate of mechanical timers is extremely high, the speed regulation of the motor is very unstable, it is easy to stall, and the use effect is extremely poor, so it cannot be adapted to farming. Households need to change feeding distance
